Respectfully I would question if that 1938 Big Pines Recreation Camp building was actually in Big Pines Park. Looking north, you can see the ridge line of Table Mountain in the picture. (look at it's shape. no ridge is like that in the Park that was a south facing slope). Looking at the ground area around the structure itself, it looks to have been around the flat area of present day Apple St, and Snowbird. It's interesting though. The Los Angeles Time had briefly mentioned a 'clubhouse area', in the Wrightwood area...different than the rec hall adjacent to the Wrightwood Lodge, which burned down in May of '37. I wonder if this was the structure. But it was mentioned as they were getting ready for the Winter Snow Carnival in the 30's, that was hosted by Wrightwood.
